Built on Proven ABB Low-Voltage Systems

Exa Power is an authorized ABB panel builder, and ABB systems are the foundation of everything we build. Rather than assembling from mixed, unverified parts, we construct our assemblies within ABB’s type-tested system designs, using platforms such as ArTu, ArTuMax and MNS-style enclosures and functional units.

This choice is deliberate. Building inside a manufacturer-validated system means the mechanical and electrical performance of the assembly has been characterised by the system owner, which makes compliance with IEC 61439 more straightforward and the finished product more predictable in service. The short-circuit withstand, temperature rise, dielectric strength and mechanical behaviour are established by the system design, not improvised for each project.

It also means our clients are not depending on a one-off build that has never been verified. They are getting a configuration assembled within proven rules, by an authorized partner who follows those rules to keep the type-test validity intact.

ABB is a globally recognised name in electrification, and that recognition has real value: stakeholders trust it, approving authorities are familiar with it, and operators around the world have worked with it. But for Exa Power the reason to standardise on ABB goes well beyond the badge. It is the engineering substance behind the name, the type-tested systems, the well-documented component ranges, the published coordination data and the established regional support, that makes ABB the right foundation for assemblies that have to perform and be supportable for decades.

Choosing components purely on price from mixed, unverified sources may look cheaper on a bill of materials, but it pushes risk onto the assembly and onto the owner: performance becomes uncertain, coordination harder to prove, and spares a lottery. Building within a single proven system family avoids that, which is why we treat the ABB platform as an engineering decision first and a brand decision second.

Type-testing is the process by which a system’s critical performance characteristics are verified by test and analysis. For a low-voltage assembly this includes the ability to withstand short-circuit currents, the temperature rise under continuous load, the dielectric strength of the insulation, the effectiveness of the protective bonding, and the mechanical operation of the assembly. IEC 61439 frames this as design verification, and an authorized panel builder inherits the benefit of it by building within the verified system.

The practical consequence is confidence. When we state a short-circuit rating or a continuous current rating, it is grounded in the verified design of the ABB system rather than in optimistic estimation. The assembly will behave under fault and load the way the design says it will, which is exactly what consultants and approving authorities want to see.

We then add the second half of IEC 61439 ourselves: routine verification on every assembly we build, so the individual unit is confirmed to be wired, insulated, bonded and operating correctly before it leaves the factory.
